Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building
The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the...

Measuring the Spatial Characteristics of Unsteady Pressures
This paper has reviewed current methods of determining spatially-averaged time-varying wind loads on wind tunnel building models. Some of the possibilities opened by simultaneous multi-channel...

The Application of Aerodynamic Model Tests to Wind Loading of Tall Buildings
The theory of the aerodynamic model test, in which the wind response of tall structures can be computed for a range of dynamic properties from a measurement of the external wind load,...

Field Experiments for Wind Pressures
A project is underway at Texas Tech University to acquire wind and building surface pressure data in the field. Objectives of the project are to obtain a reliable data base for external...

Research Needs to Resist Terrorist Attacks
The task of protecting facilities against terrorist attacks is very much a new problem for the U. S. civilian sector. Guidance as to what steps need to be taken by a municipality or a...

Improved Design Procedure for Shallow-Buried Structures to Resist Airblast Loading
Both conventional and nuclear weapons generate airblast loads of sufficient magnitude that structure survival at acceptable cost favors below grade construction. The design of shallow-buried...

Suspended Polycarbonate Shield to Defeat Terrorist Threats
The Navy Civil Engineering Laboratory is conducting research on a window concept that offers great potential for overcoming the disadvantages of blast resistant windows. The concept is...

Limiting Performance and Design by Reanalysis of Structures for Blast Resistance
Limiting performance is the absolute optimal response of a structure under a specified transient load. Reanalysis methods are computational techniques for analyzing locally modified large-scale...

Fault Identification by Seismic Impact Load Techniques
The propagation of seismic waves generated by impact loading across a normal fault in carbonate rock was investigated by the seismic refraction technique. The field records were reduced,...

Wind-Induced Response of a Tall Building and Comparisons With Wind Tunnel Predictions
This paper describes the measured wind-induced response of a tall office tower and comparisons made with wind tunnel studies of the building. The use of an innovative structural system...

Rational Design Approach for Tension on the Net Section
A study of the bearing and net section capacities of bolt connections for material thicknesses encountered in cold-formed members was conducted. This paper summarizes the findings as they...

Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...

Practical Analysis of Flexibly-Connected Building Frames
Modeling of flexible connection behavior as elastic-perfectly plastic is proposed for analysis of building frames, and results based on this idealization are compared with fully non-linear...

Centrally Loaded Columns
The paper has given a detailed description of the chapter on centrally loaded columns that will appear in the 4th Edition of the Structural Stability Research Council 'Guide...

Beam-Columns
The Fourth Edition of the SSRC Guide presents a state-of-the-art information on beam-columns for use by specification writers, researchers, and designers. The present paper is an extremely...

Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...

Effect of Connector Spacing on Double Angle Compressive Strength
The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members...

Reliability-oriented Design of Fatigue Experiments
It is well known in the reliability analysis for structural components subjected to cyclic random load that apart from the usually model parameters uncertainties are most important and...

Reliability Revision for Structures in Service
Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available....

Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...
